1 Samuel 17:10, 25-26, 36

And the Philistine said, “I defy the ranks of Israel this day. Give me a man, that we may fight together.”

And the men of Israel said, “Have you seen this man who has come up? Surely he has come up to defy Israel. And the king will enrich the man who kills him with great riches and will give him his daughter and make his father’s house free in Israel.” And David said to the men who stood by him, “What shall be done for the man who kills this Philistine and takes away the reproach from Israel? For who is this uncircumcised Philistine, that he should defy the armies of the living God?”

Your servant has struck down both lions and bears, and this uncircumcised Philistine shall be like one of them, for he has defied the armies of the living God.”
